Comprehensive X-ray Study of Giant Radio Galaxies with XMM-Newton and Chandra
Niraj Maurya, Satish S. Sonkamble, Suraj Dhiwar +3
We present a systematic X-ray spectral analysis of 27 giant radio galaxies (GRGs) using archival \textit{XMM-Newton} and \textit{Chandra} data. Roughly 44\% of the sample show intr…
Unveiling the Bulge-Disc Structure, AGN Feedback, and Baryon Landscape in a Massive Spiral Galaxy with Mpc-Scale Radio Jets
Joydeep Bagchi, Shankar Ray, Suraj Dhiwar +9
This study delves into the bulge-disc components and stellar mass distribution in the fast-rotating, highly massive spiral galaxy 2MASX~J23453268-0449256, distinguished by extraord…
LyC Leakers in the AstroSat UV Deep Field: Extreme UV emitters at the Cosmic Noon
Suraj Dhiwar, Kanak Saha, Soumil Maulick +5
We report the direct detection of Lyman Continuum (LyC) emission from 9 galaxies and 1 Active Galactic Nuclei (AGN) at 1.1-1.6 in the GOODS-North field using deep observ…
Probing star formation in five of the most massive spiral galaxies observed through
Shankar Ray, Suraj Dhiwar, Joydeep Bagchi +1
We present highly resolved and sensitive imaging of the five nearby massive spiral galaxies (with rotation velocities ) observed by the UltraViolet Imaging Tel…
Witnessing the star-formation quenching in ellipticals
Suraj Dhiwar, Kanak Saha, Avishai Dekel +4
We study the evolution of elliptical galaxies in the color-magnitude diagram in terms of their star-formation history and environment, in an attempt to learn about their qu…
Morphology, color-magnitude and scaling relations of galaxies in Abell 426
Sheeraz A. Khanday, Kanak Saha, Nasser Iqbal +2
We present photometric properties of 183 member galaxies in the Abell 426 cluster using the Sloan Digital Sky Survey (SDSS) imaging and spectroscopic observation. Detailed morpholo…
Unveiling an old disk around a massive young leaking blueberry in SDSS-IV MaNGA
Abhishek Paswan, Kanak Saha, Anshuman Borgohain +2
Extreme emission-line galaxies, such as blue compact dwarfs (BCDs), Green Peas (GPs) and blueberries in the local Universe are the potential candidates to understand the nature of…
Hubble Space Telescope Captures UGC~12591: Bulge/Disc Properties, Star Formation and `Missing Baryons' Census in a Very Massive and Fast Spinning Hybrid Galaxy
Shankar Ray, Joydeep Bagchi, Suraj Dhiwar +4
We present Hubble Space Telescope (HST) observations of the nearby, massive, highly rotating hybrid galaxy UGC~12591, along with observations in UV to FIR bands. HST data in V, I,…
SDSS-IV MaNGA: Blueberry Candidates Associated with LSB Galaxies Merger or Tidal Dwarf Systems ?
Abhishek Paswan, Kanak Saha, Suraj Dhiwar
We report here our finding of two new blueberry galaxies using optical IFU spectroscopic data from the MaNGA survey. Both the blueberries are found to be compact ( kp…
The central region of the enigmatic Malin 1
Kanak Saha, Suraj Dhiwar, Sudhanshu Barway +2
Malin 1, being a class of giant low surface galaxies, continues to surprise us even today. The HST/F814W observation has shown that the central region of Malin 1 is more like a nor…
